I do not personally, but yes, there is a single shot rifle that can have the rifle barrel replaced with a shotgun barrel.
Yes it is. It is a single shot .177 pellet rifle. It is not a BB rifle.
Generally, no. While single shot rifles MAY have the rifle barrel replaced with a shotgun barrel, reverse is not true (usually) A rifle cartridge generates much higher pressures than a shotgun shell.
The Slavia 622 is a .22 caliber pellet rifle not a .177 caliber rifle. It is a single shot Break barrel rifle. The rifle is a spring piston shooting system. To load and cock the barrel you simply push the barrel down (Break the barrel) all the way until you feel it cock. Load a .22 caliber pellet into the rear of the barrel (Breech) and make sure it's snug flush with the barrel. Load it with the skirt facing out and the dome in the barrel. Then bring the barrel back up into position and let it snap into place. AIM FIRE!
I highly suspect that the rifle has an octagon (8-sided) barrel. The October 7th, '79 patent date strongly points towards the rifle being a Browning or Winchester Single Shot rifle. The serial number on the barrel or the lower tang will help solve the mystery.
